应用加入 agora.io 频道时，AVAudioPlayer 自动停止

Question

当用户在我的应用中点击通话按钮/joinChanne(Agora) 时，我正在添加声音。

    [self.agoraKit joinChannelByToken:self.userManager.agoraToken channelId:self.userManager.channelName info:nil uid:[self.userManager.UID integerValue] joinSuccess:^(NSString *channel, NSUInteger uid, NSInteger elapsed) {
        NSString *path = [[NSBundle mainBundle] pathForResource:@"ringing-sound-jalebi" ofType:@"mp3"];
        NSURL *soundFileURL = [NSURL fileURLWithPath:path];
        self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
        self.audioPlayer.delegate = self;
       [self.audioPlayer play];
     }];

但我收到“AVAudioSession.mm:997:-[AVAudioSession setActive:withOptions:error:]：停用正在运行 I/O 的音频会话。所有 I/O 应在停用音频之前停止或暂停会话”错误。有人可以帮我解决这个问题吗

当你加入通话时，Agora SDK 似乎会自动停用任何现有的 AVAudioSessions，以确保你能听到与你通话的人的声音。我建议改为通过 Agora 的sound mixing API 播放声音。

// Plays an audio effect file.
int soundId = 1; // The sound ID of the audio effect file to be played.
NSString *path = [[NSBundle mainBundle] pathForResource:@"ringing-sound-jalebi" ofType:@"mp3"]; // The file path of the audio effect file.
int loopCount = 1; // The number of playback loops. -1 means an infinite loop.
double pitch = 1; // Sets the pitch of the audio effect.
double pan = 1; // Sets the spatial position of the audio effect. 0 means the effect shows ahead.
double gain = 100; // Sets the volume. The value ranges between 0 and 100. 100 is the original volume.
BOOL publish = true; // Sets whether to publish the audio effect.
[self.agoraKit playEffect:soundId filePath:path loopCount:loopCount pitch:pitch pan:pan gain:gain publish:publish];
